۞ And We treated with Musa thirty nights, and We completed them with ten; so the appointment of his Lord was completed by forty nights. And Musa said unto his brother Harun: act thou in my place among my people, and rectify, and follow not the way of the corrupters. 142 During the appointment, the Lord spoke to Moses. He asked the Lord to show Himself so that he could look at Him. The Lord replied, "You can never see Me. But look at the mountain. If the mountain remains firm only then will you see Me." When the Lord manifested His Glory to the mountain, He turned it into dust and Moses fell down upon his face senseless. After regaining his senses, Moses said, "Lord, You are all Holy. I repent for what I asked you to do and I am the first to believe in You." 143 [Allah] said, "O Moses, I have chosen you over the people with My messages and My words [to you]. So take what I have given you and be among the grateful." 144 We wrote advice and laws for him on Tablets about all kinds of things, saying, "Follow them and command your people to follow the good advice therein, and I will show you the dwellings of the evil-doers." 145 I will turn away from My signs those who are arrogant upon the earth without right; and if they should see every sign, they will not believe in it. And if they see the way of consciousness, they will not adopt it as a way; but if they see the way of error, they will adopt it as a way. That is because they have denied Our signs and they were heedless of them. 146 Hence, all who give the lie to Our messages, and [thus] to the truth of the life to come - in vain shall be all their doings: [for] are they to be rewarded for aught but what they were wont to do? 147
